✦ Synopsis

A method for the laboratory-scale production and isolation of chitosan (polyglucosamine) by liquid and solidstate fermentation from Lentinus edodes was developed. The yields of isolated chitosan were 120 mg/L of fermentation medium under liquid fermentation conditions and 6.18 g/kg of fermentation medium under solid-state fermentation conditions. The latter method, which gives up to 50 times yields than other chitosan production methods from fungi, provides a new flexible and easily scaledup procedure forthe production of low acetylation degree chitosan.

## Abstract **BACKGROUND:** Growth kinetics of __Pichia pastoris__ and heterologous expression of __Trametes versicolor__ laccase were compared. This is the first study of its kind between solid‐state yeast cultures done on polyurethane foam (PUF) and submerged liquid fermentations (SmF). **RESULT
